The mid-Western Zhou period witnessed significant changes in jade ornaments. In addition to those for ceremonial use, jade pendants became diversified in style and form. Jade phoenix, a bird with a feathery crown, a hooked bill and sharp claws, became a common motif. This phoenix was sometimes associated with other creatures to make a complex design. During the early Spring and Autumn, jade production followed the tradition of the late Western Zhou, showing a random style in linear carving.
